Lesson 9:Moon Phases
Half of the Moon is always lit up by the sun Half of the Moon is always lit up by the sun. As the Moon orbits the Earth, we see different parts of the lighted area. http://www.nasm.si.edu/apollo30th/moontheater/phasepage2.html
The revolution of the Moon around the Earth makes the Moon look as if it is changing shape in the sky. http://btc.montana.edu/ceres/html/birthdayphases.htm
This is caused by the different angles from which we see the lighted part of the Moon's surface. These are called "phases" of the Moon. http://btc.montana.edu/ceres/html/birthdayphases.htm
